End With ' table for chart

当我观察控制台时，我得到了id的值。

请帮忙。

我不知道问题是否已经解决，但也许其他人需要答案:)

我遇到了这个问题，在解决之前我看到了你的问题

问题来自HomePage作为您的网站教程

 constructor(public navCtrl: NavController,public player: PlayerService,public youtubeService: YoutubeService,public loadingCtrl:LoadingController) {
    player.setupPlayer();
  }

从构造函数中删除player.setupPlayer();并插入此

 ionViewDidLoad() {
    this.player.setupPlayer();
  }

我希望这会有所帮助
